Method for forwarding data packets by a router

Abstract

The invention describes a method for transmitting data packets by a router, whereby the ports of the router are assigned to affinity values. The data packets also comprise affinity values. Depending on a match of the affinity values of the data packets and the affinity values of the ports, the router forwards the data packets to selected ports. Furthermore, the data of the payload of the data packets are attenuated depending on the affinity value that is used for selecting the port.

1. In a network having a plurality of routers interconnected with each other, a program storage device readable by a digital processing apparatus and having a program of instructions which are tangibly embodied on the storage device and which are executable by at least one processing apparatus of said network to perform a method of transmitting a packet of data, said method comprising:
 determining a receiver for said packet; 
 determining an affinity value for said packet; 
 attenuating a payload of said packet depending on its affinity value; 
 determining an affinity value assigned to said determined receiver; and 
 transmitting said attenuated packet to said receiver if said determined receiver has the same affinity value as said packet. 
 
     
     
       2. A network for transmitting a packet of data, said network comprising:
 a plurality of receivers interconnected with each other; and 
 at least one program storage device readable by a digital processing apparatus and having a program of instructions which is tangibly embodied on the storage device and which is executable by at least one processing apparatus of said network to perform a method of transmitting a packet of data, said method comprising: 
 determining a receiver for said packet, 
 determining an affinity value for said packet, 
 attenuating a payload of said packet depending on its affinity value, 
 determining an affinity value assigned to said determined receiver, and 
 transmitting said attenuated packet to said receiver if said determined receiver has the same affinity value as said packet. 
 
     
     
       3. A network for transmitting a packet of data as recited in  claim 2 , wherein each receiver is one of the following: a router and host. 
     
     
       4. A router for transmitting a data packet in a communications network, said router comprising:
 a processor programmed for determining a receiver for said packet; 
 a processor programmed for determining an affinity value for said packet; 
 a processor programmed for attenuating a payload of said packet depending on its affinity value; 
 a processor programmed for determining an affinity value assigned to said determined receiver; and 
 a transmitter for transmitting said attenuated packet to said receiver if said determined receiver has the same affinity value as said packet.
